The "Writing’s on the Wall" singer earned a Best Original Song nod on Thursday for his contribution of Spectre's theme song, admitting that he was "feeling very overwhelmed and just can't believe it."

"I am sitting in a coffee shop with my mum and just found out I have an Oscar Nomination," the 23-year-old singer revealed in a statement. "Better pick out a gown. Thank you to the Academy for this incredible honor and recognition."

"I had ear plugs and all I heard was, 'You're going to the Oscars,' and she was sobbing, so I wasn't sure if it was good news or bad news!"

Lady Gaga is nominated alongside Smith in the Best Original Song category for her contribution to The Hunting Ground. The singer dedicated her nomination to victims of sexual assault, writing, "This nomination lends a voice to so many victims and their families around the world. Thank you to The Academy for recognizing the movement of people who have come together around The Hunting Ground and “Til It Happens To You” in the name of sexual assault. Diane Warren and I are simply honored to represent the voices of so many survivors.”

Sylvester Stallone, who is up for Best Supporting Actor -- his first nomination in 39 years -- for Creed, wrote: "I am incredibly humbled by this honor. I was not expecting it ... especially at this time in my life. I am certainly grateful to the artists and collaborators who helped make it possible."

And Jennifer Lawrence, who earned another nomination this awards season for her leading role in Joy, wrote: "I am beyond grateful and humbled by this nomination. I feel incredibly honored to be recognized among the other amazing women in this category. Joy is an incredibly inspiring story about an ordinary woman who does extraordinary things. For me, working with David O. Russell has been nothing short of extraordinary, and I share this nomination with him as well as our incredible supporting cast. I could not be more proud to be a part of this film and thankful to the producers and Fox for their unyielding support."

Leonardo DiCaprio was similarly gracious in accepting his Best Actor nomination for The Revenant, writing: “I am so grateful to the Academy for their recognition of this film. Making The Revenant was one of the most rewarding and collaborative experiences of my life. None of this would have been possible without Alejandro's talent, vision and determination. Our dedicated crew also deserves to share in this moment. Together, they have created a truly unique cinematic experience. Congratulations to all of my fellow nominees this season. Thank you to the Academy."

The Weeknd shared his excitement for his Best Original Song nomination, tweeting, "It can't get more surreal than this. Thank you for the recognition @TheAcademy . Truly a proud moment."

Mindy Kaling celebrated Inside Out's nominations on Instagram, writing, "I am so proud of this movie. The artists behind it thought exploring inside a young girls mind was something people would respond to, and they were right."

Meanwhile, composer Ennio Morricone, who is nominated for his haunting score in Quentin Tarantino's The Hateful Eight, revealed that he initially turned down the project.

“When Quentin first asked me to write the score for his new western, I said no. But Mr. Tarantino is an astute man, and he left the screenplay for my wife Maria to read. He had spotted who is the boss in our house," Morricone wrote. "Maria realized instantly what a brilliant screenplay Quentin had written for The Hateful Eight, and she told me in no uncertain terms that I had to do it. I am so happy that I did. To work with such a brilliant young director at my age gives me great pleasure. He was just one year old when I wrote my first score for Sergio Leone for A Fistful of Dollars. It is also a deep honour and very humbling to receive this prestigious award nomination for doing the profession I love. I receive it on behalf of myself, Quentin Tarantino, The Weinstein Company, and the whole cast and crew of this remarkable film. And of course I receive it on behalf of my clever wife Maria.”

Jennifer Jason Leigh, who nabbed a Best Supporting Actress nomination for her work in The Hateful Eight, wrote: "This is incredible news to wake up to. I am thrilled. I didn't think the experience of working with Quentin and this cast could get any more rewarding....to get this recognition for this role is such a joy."

Adam McKay, who earned both director and screenwriter nods for The Big Short, said he is “so happy for everyone who worked on this movie. This was truly an ensemble project from cast to crew to producers. Thank you to the members of the Academy and to all the audiences that have supported The Big Short. Now I'm going to take a nap.”
